SICARID-TCL a New Microwave System for the Transfer of Informations from the Track to the Wagon in Railway Networks

The transfer of information from the railway network to passing locomotives is a very important factor in all systems for automatic train control. Systems with intermittent transfer of information from fixed points to the locomotives offer in addition to the information transfer the advantage of exact locating the locomotive. Thus direct train control without reply to central control points is possible. SICARID-TCL (Train Control and Locating) is such a system operating in a broadband scanning made from 2.9 to 4.05 GHz. By applying MIC-technology with integrated semiconductor chips for the microwave moduls and the latest techniques for the analogue and digital circuitry a failure rate of lower than 10-6 with an information capacity of 1013 bit at high transmission rate is achieved.
